Nvidia refutes chip backdoor allegations as China launches probe
Chinese authorities have summoned Nvidia over national security concerns tied to its H20 chip, reviving fears of geopolitical retaliation in tech.
Nvidia has firmly denied claims that its AI chips contain backdoors allowing remote control or tracking, following questioning by China’s top cybersecurity agency.
The investigation, which focuses on the H20 chip explicitly designed for the Chinese market, comes as Beijing intensifies scrutiny over foreign tech used in sensitive systems.
The H20 was initially blocked from export in April under US restrictions, but is now expected to return to Chinese shelves.
China’s Cyberspace Administration (CAC) summoned Nvidia officials to explain whether the chip enables unauthorised access or surveillance. The agency cited demands from US lawmakers for mandatory tracking features in advanced AI hardware as grounds for its concern.
In a statement, Nvidia insisted it does not include remote access capabilities in its products, reaffirming its commitment to cybersecurity.
Meanwhile, China’s state-backed People’s Daily questioned the company’s trustworthiness, stating that ‘network security is as vital as national territory’ and warning against reliance on what it described as ‘sick chips’.
The situation highlights Nvidia’s delicate position as it attempts to maintain dominance in China’s AI chip market while complying with mounting US export rules.
Tensions have escalated since similar actions were taken against other US firms, including a 2022 ban on Micron’s chips and recent antitrust scrutiny over Nvidia’s Mellanox acquisition.
